Regulatory Accountability

The IESO is a not-for-profit corporate entity established in the Electricity Act, 1998, which is under the jurisdiction of the Ontario Minister of Energy. Its fees and licences to operate are set by the Ontario Energy Board. In fulfilling its role as the province’s reliability coordinator, the IESO must comply with, oversee and enforce reliability standards and processes that are set by several regulatory bodies within and outside of Ontario.

2017 Revenue Requirement Submission

On April 21, 2017, the IESO filed its 2017 Revenue Requirement Submission with the Ontario Energy Board. The submission and other documents which form the record of the OEB’s proceeding are available on the OEB’s webpage.

The IESO’s expenditures, revenue requirements and fees allow it to carry out its broad mandate, keeping the lights on today and into the future. This includes working with stakeholders on a Market Renewal program that is expected to achieve about $3.4 billion in savings from 2021 to 2030.
